I'm trying to put my mom's iTunes library on an external hard drive, so it doesn't fill up her 60 GB internal drive. The external drive is called 'ITUNES', and I've copied the entire library over to it, to a folder called 'iTunes music'. Inside that folder are all the folders of the different artists and inside those are her music files. Problem is, even though I've deleted those music files off her internal drive, and told iTunes Preferences to use the new location, it doesn't see those files. Do I need to drag them from the new location into the iTunes window? Or is there a button or menu item somewhere that will tell it to look on the new drive for the songs?
